- Incidence: 10.00 cases per 100,000 person-years
- Peak incidence: 60-70 years
- Sex ratio: 1:1
- Previous surgery for cataracts (accelerates posterior vitreous detachment)
- Eye trauma (consider boxing)
- Family history
- Previous history of retinal break/detachment in either eye
In infants, retinal detachment may present with a squint or a white pupillary reflex. It should be suspected if there is a history of ocular trauma with older children, as they are unlikely to comment on visual changes.
On examination, peripheral visual fields may be reduced, and central acuity may be reduced to hand movements if the macula is detached. The swinging light test may highlight a relative afferent pupillary defect if the optic nerve is involved. On fundoscopy, the red reflex is lost and retinal folds may appear as pale, opaque or wrinkled forms. If the break is small, however, it may appear normal.
